What is the current situation of valid patents in China
（1） Patent maintenance time is short, market competitiveness needs to be improved
The longer the validity of the patent right is, the longer it takes to create economic benefits and the higher the market value. According to the data, 44.0% of domestic invention patents have been maintained for 10 years, 3.2% have reached 20 years, while 82.2% of foreign invention patents have maintained for 10 years and 22.8% have reached 20 years. On the one hand, it reflects that the patents held by domestic innovation subjects are mainly "short and fast", the overall technical level is not high, and there are few core patents. On the other hand, it also shows that the innovation subjects may have difficulties in maintaining the patent rights.
（2） The level of independent innovation in high-tech field needs to be improved urgently
Although the local technology field has domestic advantages, in most fields, especially in some high-tech fields, the number of effective invention patents in foreign countries is several times higher than that in China, and the patent layout has been quite large. For example, in the fields of semiconductor, optics, control and engine, the number of effective invention patents abroad is 2.3 times, 3.2 times, 2.1 times and 3.5 times of that in China. In the process of independent innovation, the domestic innovation subject has greater intellectual property risk to avoid, and needs to find a new breakthrough point.
（3） The problem of the combination of innovation and economy in Colleges and universities is quite prominent
Statistical data show that the effective patents of enterprises have been maintained for three to eight years, and universities are mainly distributed in two to four years, which shows that the close relationship between university innovation and market is not as close as that of enterprises. The reasons for this phenomenon are that the economic interest demands of universities to obtain independent intellectual property rights are not high, the channels to enter the market are not smooth, and the problems of university innovation and economic integration have not been effectively solved. However, there are many patents with great value and good market prospects in University patents. For example, in the field of environmental technology, biotechnology and medical technology, the proportion of universities accounted for 41.6%, 41.3% and 39.9% of domestic service effective invention patents, respectively.
